Exception on a "strange" source jar #1304

Arthurm1 · 2020-01-14T13:58:52Z

I get an exception when importing a build in VSCode

To Reproduce

Include this dependency in your build "com.vladsch.flexmark:flexmark-all:0.35.10"
Import it using VSCode "Import build". Make sure source jars are included.
An exception appears in the "Output" window
Metals continues to work fine after this.

The jar structure is strange - it has a directory that has no name but 7zip can drill down into it and extract the files.

No other source jars show errors.

Installation:

Operating system: Windows
Editor: Visual Studio Code
Metals version: v0.8.0

The text was updated successfully, but these errors were encountered:

I have seen the same exception with a couple of webjars as well, but also with different folders that have not been found: /Volumes

tgodzik · 2020-01-14T14:08:27Z

Thanks for reporting! The one @Arthurm1 is connected to openhtmltopdf-pdfbox-0.0.1-RC13-sources.jar - that jar contains a weird entry coming from the library author's computer. We are unable to read that properly, but it's not an issue for Metals. @dpfeiffer /Volumes might be the same case.

This is just a warning. We might need to change that to debug, since it is quite misleading.

gabro · 2020-01-14T16:01:51Z

There's not much we can do on our side, apart from maybe handling the error in a less scary way.

I've reported the issue in danfickle/openhtmltopdf#428

olafurpg · 2020-01-14T17:09:14Z

Thank you for reporting! Metals should probably not log errors in cases like this. The error shouldn’t cause problems for metals functionality

Arthurm1 · 2020-01-14T17:11:51Z

Thanks for the info - I'll close as it's a valid warning.

olafurpg · 2020-01-14T20:35:45Z

Reopening since I think Metals should not report such noisy logs for warnings like this.

tgodzik · 2021-10-04T17:59:24Z

I reopened it since we might be able to skip the wrong directory when listing everything recursively. Let's investigate this one.

tgodzik · 2022-07-07T16:58:52Z

I haven't seen issues with this recently and just checked again to see how much effort it would be to skip the directory and it seems that would be a bit more complex, so let's leave it a is.
